Some groups in South Africa, however, worry about economic damage from plans for the expropriation of land without compensation.
The economy, one of Africa's biggest, is already in recession and struggling with problems including a weak currency and fallout from state corruption under former President Jacob Zuma.
Ramaphosa has said the ruling African National Congress party will push for a constitutional amendment to clarify the land reform process, a move that some critics believe is unnecessary and designed to drum up voter support ahead of elections next year.
Last month, Trump claimed South Africa is seizing farms and that high numbers of farmers are being killed. In fact, the South African government has not authorised land seizures and says it is still deliberating on the best way to implement land reform.
There have been some invasions of privately owned land, but these have been stopped by police.
White South Africans, who comprise about 8 percent of the population, own more than 70 per cent of the country's private agricultural land even though white minority rule ended in 1994.
The problem is more than a century old: A 1913 law allowed South Africa's black majority to own just a small portion of land, formalising a race-based system of dispossession that had been in place for decades.
When people learn about the history, "everybody gets a shock and they wonder: 'How could this have been allowed?'" said Ramaphosa, who took office after Zuma resigned early this year. The president acknowledged that "fears" remain about how land reform will unfold, though he said some concerns are dissipating.
People can't "just wake up in the morning and go and do what they like and say, 'This is my piece of estate. I'm taking over,'" Ramaphosa said. "That is not going to be allowed."
